This method is called when you close the app, so it's not visible to the end user.

This error may occur when your app is using ProGuard, and you didn't set it up propetly.

Do you use ProGuard?

[Jacek Pudysz]

Check this thread please: #151

If you're not using ProGuard, then the other possibility is that Unistyles was not loaded at all, perhaps because the app was immediately closed or crashed due to another exception, and Unistyles didn't have a chance to initialize. I can add if statement to prevent the crash.

Looking forward to your response.

@jpudysz
The ProGuard is enabled for release builds but no release build ever made, the app still in development,
Thank you.

[Jacek Pudysz]

So, did it happen during development on your machine?

Maybe it's a hot reload issue under certain circumstances. I can add one more if to prevent a crash 🙂

@jpudysz
Yes, during development on two different devices which is 100% of users for now.

Published 2.5.4 😇
